In this letter a novel lateral insulated gate bipolar transistor with a three dimensional (3D) bypass anode design on silicon-on-insulator (SOI) is proposed and discussed. The 3D bypass anode concept makes it more effectively not only suppress the snapback effect in conducting state, but also improve the switching speed as a fast electron extraction path during turnoff without wasting the anode area. Numerical simulation results show that the proposed LIGBT structure has a 1.12V forward voltage drop and 400 ns turnoff time at current density of 100A/cm(2). The proposed LIGBT saves the cell area by above 30% compared with the conventional no snapback SA-LIGBT and has about 61% reduction in turnoff time compared with the conventional LIGBT, respectively. Mostly, the proposed LIGBT can be fabricated by the conventional SOI smart power IC process without an additional process step and mask. |
